Machine learning prediction of food addiction in university students using demographic, anthropometric and personality traits
This cross-sectional pilot study utilized machine learning to predict food addiction in university students by integrating demographic, anthropometric, and personality data. Employing advanced models like Random Forest and CatBoost, the study achieved high accuracy and F1-scores, demonstrating the power of AI in identifying complex patterns. SHAP analysis highlighted psychological characteristics such as feelings of worthlessness, impulsivity, anger, and rigid cognitive styles, alongside anthropometric data like weight and BMI, as key predictors. This innovative approach offers valuable insights for early identification of at-risk individuals and developing targeted interventions for nutritional behaviors.

Identified Key Predictors for Food Addiction
Psychological Vulnerabilities Driving Food Addiction
The study's SHAP analysis revealed that psychological and emotional state variables overwhelmingly dominate food addiction prediction. The most critical predictor was 'Sometimes I feel completely worthless', highlighting the central role of low self-esteem and a negative self-concept. 'When I am under a lot of stress, I sometimes feel like I am falling apart' was also highly ranked, indicating stress intolerance and emotional dysregulation as key differentiators. Traits reflecting high impulsivity ('If necessary, I can skillfully use others to achieve my goals') and hostility ('I often get angry about how others treat me') also emerged as significant, linking interpersonal sensitivity and relational conflict to addictive eating patterns. Conversely, positive affect ('I am a happy and good-spirited person') showed a risk-reducing effect, and conscientiousness ('I can organize my tasks well to get them done on time') a mild protective influence through improved self-regulation.
Anthropometric Indicators: Supporting Role in Prediction
While psychological factors form the core of the predictive model, anthropometric indicators such as 'Weight' and 'BMI' also remain significant. 'Weight' ranked higher than 'BMI', suggesting complex interactions the CatBoost algorithm captured. This confirms the bidirectional relationship between physical status and food addiction risk, although psychological and emotional vulnerabilities are stronger predictive factors than physical outcomes themselves. This indicates that while physical attributes correlate, underlying mental states are primary drivers.
| Aspect | Traditional Statistical Methods | AI/Machine Learning Approach (This Study) |
|---|---|---|
| Data Analysis Capability | Limited in analyzing multidimensional data, often focuses on linear statistical relationships. | Effective in analyzing multidimensional data, identifying complex non-linear patterns and interactions. |
| Addressing Class Imbalance | Prone to biased predictions on imbalanced datasets, requiring specific adjustments. | Addressed using Tomek Links & SMOTE for robust training and improved minority class prediction. |
| Model Interpretability | Often straightforward interpretation of coefficients. | Enhanced with SHAP analysis for transparent, fine-grained explanations of feature contributions. |
| Predictive Power | May not fully capture intricate interactions and high-dimensional relationships. | Superior performance (e.g., ensemble methods) for early identification of high-risk individuals and complex behavioral patterns. |
Acknowledged Study Limitations
This pilot study acknowledges several limitations: a relatively small sample size and pronounced class imbalance increase the risk of overfitting (addressed with specific techniques but still a factor); the cross-sectional design precludes causal inference; and the absence of external validation limits generalizability. Furthermore, reliance on self-report questionnaires may introduce response bias. Future research should employ longitudinal designs, multicenter samples, and objective data collection methods to overcome these limitations.
